Full marathon again

It was held under clear sky with warm air.
The course was along the river called ARAKAWA river to the Tokyo Sky Tree, 42.195 Km.
Approximately 17,000 people gathered to run.
So I went through the start gate 18 min behind the front runners.
The course was flat and easy to run ...... until 30 km.
After 30 km, my right calf muscles were getting weak and I felt pain there.
But I continued to run to the 35 km aid station with low speed.
After that another myself started to whisper "stop and walk,stop and walk".
Wow the bad time had came, I thought.
I needed to fight against another myself and the calf pain.
Last 2 km was worst, I had repeated to run and walk.
But finally ,I made it. I went through the goal gate with the time of 5 hours 34 minutes.
It was very hard for me to run the full marathon.

Next time ? Not soon but I will !
